SAMUEL SHOE-MAKER, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE PENN-SYLVANIA STEEL RAILWAY TIE COMPANY, OF PHILADELPHIA, PENNSYLVANIA,

A CORPORATION OF DELAWARE.

METALLIC RAILWAY-TIE.

To all whom it may concern:

Be it known that I, SAMUEL SIIOEMAKER, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Metallic Railway-Tie, of which thefollowing is a specification.

My invention consists of a novel construction of a metallic railway tie,which is simple in construction, positive in operation, cheap inmanufacture, and which will be reliable, efficient and exceedinglydurable under all conditions, my novel tie being constructed from ametallic blank, having its body portion preferably slightly narrowed andflanged downwardly and its ends provided with corrugations of differentlengths, which are bent inwardly, downwardly, then inwardly on a linesubstantially parallel with the body of the tie, then upwardly, andfinally inwardly to form a flange or terminal contacting with the bottomof the body of the tie, the juxtaposed or contacting surfaces beingsecured in place by riveting or other means to the under side or bottomof the body of the tie, whereby a very strong and durable corrugatedanchoring member is formed at each end of the tie which is adapted to beembedded in the ballast of the road-bed.

The invention in all of its details will be fully understood from thefollowing description and claims considered in connection with. thedrawings accompanying and forming part hereof, it being understood thatvarious changes in the form, proportion, size and minor details ofconstruction, within the scope of the claims, may be resorted to,without departing from the spirit or sacrificing any of the advantagesof the invention.

In the drawingsFigure 1 represents aplan view of a blank employed inmaking my novel. construction of metallic railway tie. Fig. 2 representsa plan view of the blank after the first step of its manufacture,showing the central bod ortion flanged downwardly, and the outerextremities cor rugated, preparatory to being bent inwardly, downwardly,inwardly, upwardly and inwardly.- Fig. 3 represents a plan view of thefinished tie. Fig. 4 represents a side elevation of Fig. Fig. 5represents a Specification of Letters Patent.

Referring to the drawings :-1 designates a blank of steel or othermaterial from which my novel construction of metallic railway tie isproduced, said blank being subjected to the following operations, whosesequence, however, may be varied according to requirements.

In carrying out my invention, I take the blank 1, and preferably bysuitable pressing or rolling mechanism, I form at each end thereof thecorrugations 2, 3 and 4, it being apparent that the portions 5 near theends of the tie body are of substantially the same width as the originalblank 1, the portion 6 being slightly narrowed therefrom down to thewidth of the portion of the corrugated parts, .4 3 and 4:. The outerextremities 7, of the tie, are left blank to form a flange or terminalwhich is subsequently riveted to the bottom of the tie as will beexplained, the width thereof being substantially the same as the widthof the parts 2, 3 and t. The body 8 of the tie is provided by suitablepressing or rolling mechanism with the downwardly projecting flanges 9on opposite sides thereof, the extent of which will be apparent fromFigs. 4 and I next bend the portions 6 on the line 10 inwardly, as willbe understood from Fig' 4, against the bottom of the end portion 5 ofthe tie body, and then deflect the portion 2 downwardly on the line 11at an angle to the tie body or into the position seen in Fig. l. I nextdeflect inwardly the portion 3 on the line 12, as will be understoodfrom Fig. 4, on a line substantially parallel to the tie body, and nextdeflect the portion 4 on the line 13 upwardly or at an angle to theportion 3, as will be understood from Fig. 4, and lastly, deflect theportion 7 on the line 14, thereby forming a terminal or flange,contacting with the body of the tie, so that the parts now appear asseen in Figs. 4 and 5, the portions 6 and 14 being secured to the bottomof the body of the tie by means of rivets 15 and 16 respectively, whosenumber may be increased or diminished according to requirements.

It will be understood that both extremities of the metal tie blank willbe treated in the same manner as already described, the ends thereofbeing first corrugated and then bent inwardly, downwardly, inwardly,upwardly and inwardly, so that a description of the method ofconstruction of one end, will be suflicient for both.

17 and 18 designate preferably square holes arranged out of alinementnear the ends of the body portion 8 of the tie, the same being locatedin proximity to the abut ments 19 and 20 respectively, which latter areformed by suitable pressing or rolling mechanism from the body portion 8of the tie.

It will be apparent that a metallic railway tie made as described can becheaply manufactured, since all the parts are preferably integral withthe body port-ion and that the same will be exceedingly durable andeffective under all conditions. By making the projecting bottom oranchoring portions 2, 3 and t, seen in Figs. 4: and 5, corrugated, andsecuring them to the body portion 8 in the manner described, by rivetingor otherwise, a very strong, durable and rigid construction is produced,whereby the tie can be eifectively anchored in the ballastof theroad-bed. Furthermore, by doubling or folding the portions 5 and 6 uponeach other in the manner described, the ends of the tie will bereinforced and not readily distorted, and further by reason of theflanges 9 the tie body will be maintained in a rectilinear line underall conditions. By locating or bending the terminals or flanges 7 in theposition seen in Figs. 3 and 4:, and riveting the same as described, theouter portions of the body of the tie will be materially strengthenedand reinforced, as is evident, it being apparent that the width of theterminal or flange 7 is slightly less than the distance between theflanges 9 of the bottom portion, as will. be understood from Fig. 3.

In the construction seen in Fig. 9, I have shown a modifiedconstruction, wherein the completed tie, seen in Figs. 3, 4' and 5 isused in a reversed position, the body portion 8 with the side flanges 25thereof being embedded in the ground or ballast when in use, while theprojecting portions formed by the corrugated members 2, 3 and d serve asa cushion or chair to support the rail, suitable abutments 21 and 22being employed in proximity to the rail holes 23 and 24:. In theconstruction seen in Fig. 9, the flanges 25 are deflected in a directionopposite to the flanges 9, seen in Figs. 3, 4 and 5-2'. 6., 1n adirection away from the projecting portions formed by the corrugatedmembers.

It will be apparent that the operations whereby my novel tie is producedfrom the blank 1, can be effected by suitable pressing or rollingmechanisms, and may be performed in different sequences orsimultancously; that is, the production of the flanges 9 and thecorrugations 2, 3 and 4 can be performed simultaneously or successivelywithout departing from the spirit of my invention.

It will be apparent that by the employment of the corrugations invertical the webs 2 and d, the same are rendered exceedingly stifl andrigid, as are also the bottom members 3, whereby a very rigid anddurable anchoring member composed of the portions 2, 3 and 4, isobtained.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is:
